I used the Schwartzian Transform: 
#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

my @words = qw( fanfare apparate panacea parmesan albatross
                albacore false vermeil candelabra beans );

say for map $_->[0],
        sort { $a->[1] cmp $b->[1] }
        map [ $_, join q(), /[aeiou]/g ],
        @words;
